They'd benefit least from people knowing more about sausage and the making thereof. And legislators definitely shouldn't be robbing the First Amendment to pay for better information, as a few California lawmakers are attempting to do.
A new bill, pointed out by the EFF's Dave Maass, seems to be a response of sorts to "fake news" and other political detritus of this highly-partisan system. Ostensibly, the bill is aimed at keeping voters from being misled on issues that affect them. The problem is, this bill would allow the government to determine what is or isn't misleading and apply to a citizen's social media posts, blog, etc.
